SHUTTER-HINGE.

SPECIFICATION forming part of Letters Patent No. 525,843, dated September 1l, 1894.

Application tiled January 31,1894. Serial No. 498.625. (No model.)

.To all whom it may concern,.-

.Be it known that I, ALFRED O. ELZNER, a citizen of the United States, residing at Cinclnnati, Ohio, have invented new and useful Improvements in Hinges for Shutters, Screen- Doors, dac., ot' which the following is a speciication.

My invention relates to hinges of shutters, screen-doors, dac.; its object being to provide a cheap and simply. constructed hinge adapted to general use in house-building; having, in addition to its ordinary functions, a capacity of retaining the shutterin any desired radial position within the range of its ordinary rotative movement.

To this end the invention consists in a hinge provided with a locking device adapted to temporarily connect and retainthe pintle and corresponding socket of the hinge plates in any desired radial relation; capable of ready change of adjustment as maybe desired.

The nature and constructive features of the invention will be more clearly understood by reference to the accompanying drawings, in which- Figures l, 2, and 3 exhibit a complete elevation, (an elevation partly in lsection,) and a complete plan view, respectively, of a hinge or parts of connected hinge plates, with the locking device in preferred form applied thereto. Figs. 4, 5, and 6, exhibit acomplete plan, complete elevation, and an elevation partly in section, respectively, of a modified form of device; and Fig. 7, exhibits two corresponding detail horizontal cross-sections on p lanes m and y of Fig. 6 showing construcnon.

Referring now to the drawings, the two sets of igures enumerated are intended to exhibit two general types of construction in which the principle of the invention may be realized in practice, either of which types may include various mechanical modifications. v

In the first and preferred type, represented in Figs. l, 2, and 3, the essential principle of invention is in a key or bolt passing through the wall of the pintle-socket and engaging the pintle, as a lock against the inte r-rotation of these elements.

The construction exhibited, which is preferred for simplicity of construction and operation, is as follows: The two hinge-plates A, B, are cast or formed in the usual manner;one being provided with avertical pintle, a, and the other with a corresponding socket, h, adapted to tit over the same. Both pintle and socket are extended somewhat higher than nsual,-the pintle being provided With a diametrical recess, a', opening upward, and the extension, h', of the socket being somewhat enlarged, and provided with opposite radial recesses, h2, corresponding and registering with the recess, ai', of the pintle. The pintle contains but one diametric recess, while the socket-extension may contain any number consistent with proper strength of parts, arranged in symmetrical radial relations. To the pintle hinge-plate, A, is pivoted a suitable key or locking fingerFsWinging in the plane of and adapted to enter the diametric recess of the pintle, in one of its ultimate positions, as shown in full lines in Figs. l, 2, and 3; and arranged to hang approximately vertical when out of engagement, as shown in dotted lines in Fig. l. The pivot of the key being below its normal axis, gravity retains it in either of its ultimate positions. The key, F, is provided with a projecting lip, f, at the rear end, as shown, for convenience of manipulation. Suitable provision is made for the lateral space occupied by the key, F, when the hinge-plates are shut together; but, as the width of the key is very little, (sheet steel being the preferred material of constructiom) this is accomplished by increasing very slightly the odset of the pintle and socket, respectively, in relation to the face-planes of the hinge-plates respectively.

The operation of the device will be clearly apparent upon considering the construction shown in Figs. l and 2, and mode of attachment shown in Fig. 8. As the key, F, is in permanent radial relations with the pintle, it is attached to the pintle-plate A; and the latter, as is usual, is attached to the window casing, C; while the socket-plate, B, is attached to the shutter, D. Fig. 3, exhibits these parts and the shutter in locked position partly open and under control of the locking lever, F. To close the shutters, the key is thrown permanently out of engagement into the position shown by dotted lines in Fig. 1, by depressing the rear end of the key, F, by means IOO of the finger upon the lip, f. It' the shutter is to be locked in any intermediate position, or in fully open position, the key is first released and again thrown into engagement when the proper position is reached.

The type of structure shown in the remain ing figures does not differ in principle. In this case,.the locking key is an annular element engaging wholly outside of the pintle and outside of the socket element. As shown herein,the upward extension, b2 of the socket, b, is formed with an external periphery of polygonal cross-section (preferably with con- Vex faces) as shown in section vi Fig. 7. The pintle a is extended upward beyond the socket 212, and squared, as shown at a in section w, Fig. 7. Over these is fitted an annular cap, F, with its opening cavity fitted to engage over the socket, h2, and its inner or countersunk recess fitted to engage the squared extension of the pintle, a', all as clearly shown in vertical section Fig. 6, and cross section, in Fig. 7. It will be readily perceived, that by lifting the cap above its engagement with the socket, b2, the shntteris allowed to swing freely; and that on being depressed, into engagement with the socket, b2, rotation of the shutter in relation to the pintle, a, is prevented.

I may provide, as a convenience, not essential to the operation, a lifting lever, g, pivoted to the socket hinge-plate, as shown in Figs. 4, 5 and 6, and bifurcated at rear to engage an upward extension f of the cap, F. The lever, g, may be provided with an upward bellcrank extension, g', as a lip for convenient manipulation,so as to be easily reached (as for example, in opening the shutters slightly, to be retained in partly open position) by hand from within an apartment. The lever is alsoa means of preventing the cap, F', from becoming detached while the shutters are in use. To this end, a paw1,1t,is pivoted to the plate, B, beneath the lever, g, and normally rests against a lug, h', so as to project into 4thrown up and entirely release the cap, F.

A further feature of this type of the device is a cam projection, m, upon the hinge-plate,

B, engaging a lug, fn, projecting radially from the cap, F. The function of these parts is to lift and hold the cap, F', out of engagement when the shutter is closed; thus holding the locking device outof engagement until the shutter is opened far enough to enable the attendant to reach the cap or its lever so as to control its operation.

I claim as myinvention and desire to secure by Letters Patent of the United Statesl. A shutter-hinge embodying a pintle provided with a diametric recess, a socket provided with a series of corresponding diametric recesses, and a bolt or key attached tothe pintle member and adapted to be thrown into the diametric recess of the pintle and corresponding diametric recesses of the socket, selectively, to lock the pintle and socket members against rotation, substantially as set forth.

2. A shutter hinge embodying a pintle provided with a diametric recess, a socket provided with a series of corresponding diametric recesses, and a key or bolt pivoted below its normal axis to the pintle member and adapted to be oscillated upon its pivot into or out of engagement with the pintle and socket, and be retained by gravity in either position, substantially as set forth.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
